Put an idea through three independent checks before you trust it

Paste a claim, idea, decision, or short description. SignalWitness runs three independent reviews, then shows what holds up, what raises concern, and what still needs verification.

Three independent reviews. One clear Signal Read.

How each review works
Three mandates. One submission.

Each review runs independently with a different analytical mandate. They never see each other's work.

Review 1 · GPT-4o
Logic Check

Evaluates the logical coherence, internal consistency, and falsifiability of what you submitted. Looks for unstated assumptions that affect whether the reasoning holds.

Review 2 · Gemini
Edge-Case Analysis

Identifies failure modes, adversarial interpretations, and scenarios where the reasoning breaks down. Stress-tests it so you don't have to find the gaps yourself.

Review 3 · Claude
Synthesis

Weighs the logical validity against the edge-case concerns and produces a balanced final assessment. This is the review that anchors the Signal Read.

SignalWitness is a thinking tool, not a truth machine. The reviews identify what holds up and what needs more work — they don't determine whether something is factually true.
